Star Wars: Episode VI - Return of the Jedi (1983)

Originally called "Revenge of the Jedi", it was changed to "Return of the Jedi" because Jedi don't seek revenge. Darth Vader and the Empire are building a new, indestructable Death Star. Meanwhile, Han Solo has been imprisoned by Jabba the Hutt, and Luke Skywalker has sent R2-D2 and C-3PO to try and free him. Princess Leia - disguised as a bounty hunter - and Chewbacca go along as well. The final battle takes place on the moon of Endor, with it's natural inhabitants, the Ewoks, who befriend and lend a hand to the rebels. Meanwhile, during the battle, Luke faces his final showdown to defeat the Emperor and restore the goodness in his father.
